    Strong as a brick? I think not. You need to beef it up to at least 5 if not 6 layers to be able to use a decent amount of bands. I made a layer crossbow that shot real arrows, straight into my bedroom window, unfortunately... >.>

    One idea would be to use a thick bow, so it does not bend or snap off, thus allowing for more elastics/bands which equals more range and power. And another idea would to have the gun atleast 5 layers thick, and a well designed barrel such as the SR-V2's design or the Siprianis's design. And use the trigger system off the SR-V2, it allows for the most power. Those are just my ideas.

    *PS: It really needs a handle.

    Thanks for the advice, i have designed a new trigger mec. that is better than the other. i'll send pic soon


    Crossbows dont have handles you just hold on to the stick thing if you add a handle it wouldnt be a crossbow


    im also making another 'ible with mods and extra's so i will put a handle and different trigger if u want
    what did u rate it?? i am very interested
    if it means getting more stars, i will add/remove/edit anything in my crossbow. i hope u hav read everything here


    There is no handle - i based it on a medieval design i saw on a tv show called merlin (bbc one saturday 8pm)

    I rated 3.5*, it's good, but not the best. I think you could improve the strength of the bow a bit, it looks a bit weak. Otherwise, it's pretty good
